AUTOMOBILE RADIATOR.

`Apjgilicatoii filed December 26, 1919.

To a'ZZ whom tmf/ty concern `Be it lrnown'that I, Roemer R. SWANEY, a citizen oit the United States, residing at Sacramento, inthe county of Sacramento, State of California, .have invented certain new `and useful Improvements in Automobile Radiators;` and I do declarethe following 4to `be a fulhclear, and exact description of the same, `reference /beinghad to the accompanying drawings, and to the characters vof reference marked thereon, ywhich torni a part of :this application.

This invention relates to improvements in radiators, being adapted to be used for cooling the cylinder-jacket Water `of internal combustion engines of all `kinds, Whether used for automobiles, tractors, trucks, aeroplanes or similar purposes.

It is also adapted to be used ttor condensing purposes in connection with steam boilers and lthe like.

The type of radiator is `that known as thelioney comb type, on account of the shape .or its core, the principal yobject ofthe -inmention being to devise a radiator otthis type Which Will be stronger than the yradiator as now constructed, and yet Amore Hexible.

.another object is to construct and position the Water passages so that the Water must traverse a relatively longer distance `for a given height of radiator than is had with present radiators, and in which as a conse Vquence the Water is subjected to the cooling air or other' medium tor a longer period Aduring its passage through the radiator, and

more Water can therefore ibe Vadequately cooled yin a given space.

The radiator passages are also arranged so that the Water in passing therethrough will be agitated and churned, thus alternating kthe layers of Water vthrown against the cooling surfaces and 'further enhancing the cooling processes.

I am also .enabled to have a greater num ber of- Water passages or tubes in a given width than is .otherwise possible with the same Width of cells or tubes.

Vith my radiator construction, there is no tendency i'or sediment to depositl or collect in the Water passages, which would of course Specifica tion of Letterslatent.

`Fig. e lis a fragmentary sectional View of another `torni of `Water passage construction.

Referring now more particularly to the characters of reference .on vthe drawings, l denotes in general a section of the `radiator structure, there being as many such sections as are necessary to attain the ,desired `width ot radiator, and each section lbeing the ,lieightdesired for the radiator.

inasmuch as the `results I obtain `withzmy radiator construction are due solely to y.the method oi building lup or Weaving the'sections, l Will now describe this method.

IIn common with `radiators of `the honey comb design, the sections -are each formed of an endless strip of sheet metal 2 Whose width is that of the radiator. In Weaving a section, vlet us presume that the vstart is made at A (see Fig. 3). The sheet metal from `this .point extends straight for a certain ydistance yas at B and `is'then bent up at right angles `as at C, the ylength of the portion C being one-third the length of the strip B. At 'the end of the portion C the strip bends again parallel yto the portion B and inthe same plane las at D, `which last portion is `the same length `as the portion C. A right angle bend E is then Imade to the strip B, thus forming a square cell 'At the point of junction of the portion E with the strip B tie metal E2 extends parallel to and adjacent. said strip as at l?, and is then bent up at 1ight angles as at (i, each such bend being of the same length as any side of the cell 3. At the termination of the portion G the strip is bent at right angles and extends over the edge l) of cell 3 as at H to a distance therebeyond equal to the length of one side of the cell, which length it will be seen is equal to that of strip B.` From this point the metal is again bent up to form a. side I equal and corresponding to the side (l of cell 3, and the operation repeated until the section attains a height desired for the radiator.

l/Vith the bending of the portion H, a cell l is formed alongsidecell 3. It will also be noted that there are three thicknesses of metall along one edge of each alternate cell, as shown at 5. I have therefore formed a cell or section structure in which each pair of cells is odset or stepped one cell from each succeeding pair, and in the same direction.

Therefore when the section is positioned in a vertical piane, the outer and opposite corners of each pair of cells will lie in a horizontal plane. This makes for a very flexible construction and one which stands strains and shocks without fracture.

Each such opposite and outer edges of each pair of cells is recessed as at 6, such recesses being set back from the outer ends of the cells.

The radiator as stated, is built up of a number ofvsections, the offset cells of cach section resting adjacent the cru-responding cells of the adjacent section. It will thercfore be seen from Fig. 2 that the recesses of one section are in horizontal alincment with the sharp inner corners of the stepped cells of the adj accntsection, and so on throughout, so that a staggered effect is had from top to bottom of the radiator, and a zigzag water passage? is formed, which causes the water to be agitated or churned during the passage therethrough. y

Each recess of course extends on each side of the edge of the cell for a distance somewhat greater than half the length of aside, so that an open passage will always be had between adjacent recesses, as at 8.

The sections are combined in the usual manner, that is, by clamping the same rtogether, and dipping theA entire structure in solder, so that all the thicknesses of metal are `sealed together at both ends and for the entire width of the radiator as well, along all the abutting thicknesses at K in Fig. 3, the .radiator when thus dipped pren senting an unbroken appearance, as shown in Fig.V 1. -By arranging or positioning the cells soo-that they are diagonal, I obtain a greater number of water passages for a given width of radiator than can otherwise be had,

Lair/,ves

and hence a greater amount of water can be cooled.

In the form of construction shown in Fig, Il, the alternate recesses 6 are dispensed with, and a proportionate width of each outer cell surface merely flattened slightly as at 9, so that the adjacent section, correspondingly treated, will form therewith a zigzag water passage l0. The weave and method of binding together of this structure is the saine as that previously described.

lilith either type of construction, should a leak in any section or cell occur by acci dent or otherwise, it is only necessary to plug up the two opposite ends of the cell or cells affected, the water passages not being affectedA in any way.

From the foregoing description it will be readily seen that I 'have produced 'such a device as substantially fulfills the object of the inventionas set forth herein.

l/Vhile this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is 1. A honey-comb radiator consisting of a plurality of sections, each section comprising vertically disposed rows of square cells positioned to lie with their opposite corners in vertinl and horizontal alinement respectively, the cells of each section being fitted in with those of adjacent sections, and continuous water-passages formed between the sections through which a straight vertical. line may be drawn.

2. A- honey comb radiator comprising a plurality of sections, each section comprising square cells arranged in pairs, each pair being offset one cell from the adjacent pair and in the same direction whereby when the sections are set vertically the opposite corners of each pair of sections will lie in a horizontal plane, and water recesses formed in such opposite edges, set back'frorn the outside ends thereof.

3. A honey comb radiator comprising a plurality of sections, each sect-ion comprising square cells arranged in pairs, each pair being offset one cell from the adjacent pair and in the salie direction whereby when the sections are set vertically the opposite Icorners of each pair of sections will lie in a horizontal plane, and water recesses in such opposite edges, set back from the outside ends thereof, the sections being adapted to lie adjacent and be secured to each other along` their outerv edges, and the recesses formed in the outeredges of each section forming a continuous water passage.

e. A radiator comprising rectangular cells positioned vertically7 but with their opposite corners lying in vertical and horizontal planes, each vertical rown oi cells having- Water passages formed along one set of hori- Zontally opposed, corners in vertical staggered alineinent with the similar passa-ges on the adjacent ronT and set back from the ends of the cells, said recesses being made by forming tlie inetal inwardly along said co1'- ners with the corners as Central axes, Whereby 'the position oli the metal. so 'formed is reversed from its normal setting'.

In testimony whereof I aliix my signature.
